Hello John and all:

One of the things that I haven't seen covered about BPL, is the
installation and maintenance costs involved, in a power grid system.

We all know that when a system is modified for something that it wasn't
designed for that problems will surface. I'll bet money that the power
grid system modification and maintenance may be have a significant cost.
That was not totally covered, or audited.

From all I have seen, nothing is modified, a tap is made and BPL
installed. The power grid stands as before ... however, the system I
looked at was almost entirely underground to businesses and homes.

An interesting point! And did this underground system radiate at HF??

It seems to me that if a BPL system can be made that doesn't radiate at
HF, then I have no problem with it.

Martin:

It is the house lines which have some amateurs worried, unless you have
an underground home, or all lines are run through properly shielded
conduit (NOT likely!), this is what worries most amateurs ...

Although I use 10/11 meters daily and 80 meters 2/3 times a week, most
of my operations have moved vhf/uhf/shf. I think that is the future.
HF simply servers too few to demand the consideration some wish.

We've all heard the nightmare stories and seen the enforcement actions
taken against Power companies that can't be bothered to fix a broken
insulator, bad ground wire, noisy transformer, or whatever that is
causing havoc to hams nearby. If they do put in BPL, it will be their
very own customers who complain to them. Then they have less of a
choice, assuming they want to keep their BPL customers.

And they still have to run the fiber. Why don't they just try selling
fiber access? Somewhere somehow we got a popular misconception that
there is some sort of magic box at the power generating station that
supplies internet access to the world. It ain't so.
